9 Claims. (o1. es-94) This invention relates to ventilators. It is old in the art to provide ventilating panels carrying an exhaust fan and adapted to be attached to the upper part ofa window case- -ment to permit the "fan to exhaust the warm air,

steam and odors of cooking from a kitchen. These prior art devices of which- I am aware, are disadvantageous for'the reason that their installation in the window casement interferes with the operation of the window sash,- first in that the upper sashcannot be completely elevated to its normal position, and second that the lower sash cannot be fully opened when it is desired to do so. 15

My present tilator of this kind and an arrangement for supporting the same in a window casement, the

of the sashes of the window. accordance with the teachings of my present in ufactured and installed, thereby rendering it additionally advantageous over theprior art devices.

-The invention can be best understood reference to the accompanying drawing in which;

Figure 1 is'an elevational inside view'of a win- .dow casement with the ventilating panel of my I sash 21 throughout its entire path ofitravel; sincej invention installed therein.

ure 2 is a cross sectional view'along th 11 -2 of Figure 1; r

Figure 3 is a fragmentary cross sectional view .taken' along the line 3-3 of Figure 1; and

Figure 4 is a perspective view of the mounting bracket of myinvention.

-Referring now to the "drawing in more detail, the ventilator of my invention consists of a me-" .tallic panel 1 having overturned'edges into which retractable end pieces 3 and 4 are registered. The main panel 1 is provided in a standard length which fits into a majority of the windows, an ac curate fit being accomplished through the ex tension of the members 3land 4 intoregistration with the stops of the window casing. Centrally located in' the 'main panel 1 is an opening opposite which the fan 5 is positioned, that fan preferably being a fan of thefso-called exhaust type having'a ring which is ad'ap'ted to be attached to the panel member 1 in any convenient manner such as by bolts 7. Rising'out of the lingo are arms 8 which extend toward the center oi the" frame and join with the motor casing 9. in which is located an electric motor by which the fan 5. is revolved: The particular details of construe invention has for its principal object the provision of a new and improved venthe free end of the mounting erial No; 513,507.

' the present invention and maybe varied within the teachings thereof.

Located near the upper edge of the'main panel j member 1 are slotslO and 11 by which it is hung in the easement 12 of the window.

As will be best seen in Figure 2, the tongue 13 of the supporting hooks 1fl1are projected throughj' these slots 10and 11 to permit the panel to hang in the Windowop'ening; i

These supporting brackets are composed of a mounting plate '15co'ntaining a plurality'of countersunk holes 16 through which screws 17 of the windowcasing.

Projecting out. of themo ting plate 15 is a semi-circular projection 19terminatingin the j tongue 13upon which the panel hangs, this semi? circular [portion -19 "spacing the tongue "away are projected to attach the hooks to the stops '18 from the mountingp t l dfandholding itparal 751 lel to this plate. I p

in mounting thebrackets 14 in" the window casing, niodntingplates 15 are placed'on the stops 18 in such position thatthe outermost edge 5 of the semicircular projection 19 lies just in side of the track 20in which the upper. sash 21 of the window moves. hook'to' the window casement in thisl n lanner obviously permits free movement of thef'uppen the. hooks are disposed completely on the inward" or room side of this path. j The free end of the tongue 13 extends beyond I plate 15 and is turned upslightly asshown at 22'. to, providef a hook-like. end on the tongue, this end being useful in preventingfthepanel from sliding off of the hook as will presently appear. '1 i After the hook has' bee n" placed ,upon the win dow casing in the foreg'oing manner'andproperly spaced thereon so'that the tongue-s13 will register with the slotslo and 11 in the panel,

the panel. is installed in the, window by simply hanging it upon these hooks." Because the motor housing" 9 and brackets 8 of the fan mechanism project from one side of the panel 1, that panel, when free to swing, will hang atan angle'with" respect to a perpendicular, as is seen in Figure 2'." Thus'it will be'seen that when the'panel is pushed on the tongues 13'so that it abuts against the semi-circular closed ends 19 0f thebrackets, I the lower end of the panel'wilLfif free'to do so, swing over into the path of the upper'sash 21. Thus when the uppersash is lowered and the panel installed, the sash can'be raised'slightly PATENT -o*FF1cE-jf The "attachment 'of the; 1

to bring it into registration with the lower edge of the ventilating panel, thereby closing the opening at the top of the sash and permitting the upperedge of the upper sash 21 to aid 5 in the support of the panel in the window opening. By extending the side members 3 and 4 into engagement with the side stops'22 of the,

windowcasing, the opening can be completely blocked and thereby made to present a neat and orderly appearance. The installation is completed by simply attaching the electric cord which is extended to the motor to a convenient outlet and the panel is thereby rendered ready for use.

During stormy weather and at other times when it is not desired to exhaust air from the room, the upper sash 21 can be raised fully by simply drawing the panel 1 back upon the'tongues 13 of the brackets, to thereby bring the panel out of the track of this sash. The sash is then raised and when the panel is released itslower edge rests against the side rails of the sash, because of the overbalancing of the panel by the motor assembly.

Of course when the panel is thus positioned in the top of the'window, it is impossible to completely raise the lower, that is the inner sash of the window, and when it is desired to completely raise this sash, such as, for example, when s, the window is to be cleaned, the panel 1 is pulled inwardly of the window on thetongue 13 to bring it out of the path of the lower sash, thereby permitting that sash to be raised until its upper 1 edge strikes against the tongue '13. Since the tongue' projects downwardly from the top of the window only a' very short distance, the lock mechanism on the top-of the sash will strike against the upper stop 18 at practically the same time that the top rail of the lower sash strikes Q the tongue 13, so the windowfcanbe raised as high as it could if the'brackets 14 were not installed. Since the tongue 13 extendswell inside of the path of the lower sash, the panel can be. moved sufficiently far to permit this sash to be fully operated without detaching it from thefsup'porting brackets. The hook-like ends 22 of the tongues prevent the panel fromaccidentally sliding off the hooks during this operation.

If for any reason it is desired to completely 9; remove the panel from the window, theelectric cord is detached and the panel lifted' off of the tongues 13 of the supporting brackets thereby V freeing it and permitting its removal.

From the foregoing it will be apparent that 5 1 have provided a new and improved ventilat- "ing panel which can-be economically manufactured since it is composed largely of sheet metal, and which panel can also be conveniently and at the same time securely installed in the win- Qwdow, this installation providing for the full operation of the window sash when necessary to do so, and also providing for the convenient removal of, the panel from the window, if desired. While I havefchosenfto show my invention 6- :;fby illustrating a preferred embodiment of it, I have done so by way of example only, as there are many modifications and adaptations which can be made'by one skilled in the art, without departing from the teachings of the invenition, and I am therefore not to be limited by the specific'disclosure, but rather only by the scope of the appended claims.

What is claimed is: 1. 'The combination with a window having'an f inner and anjouter sash mounted in a frame and sash and terminating adjacent the inside edge of "said main portion and located parallelto it, said separated by stops, of a ventilator comprising a panel upon which a ventilating means is mounted, and a pair of U-shaped supporting hooks having one of their sides attached to the stops located on opposite sides of the inner sash and at the top of the window frame, said stops being mounted with their closed ends outward, the free sides of said hooks projecting through slots in the panel to hang it in the window, said ventilating means overbalancing the panel to cause it to hang with its lower edge in the plane of the outer sash.

2. The combination with a window having an inner lower sash and an outer upper sash mounted in a frame and separated by frame stops, of a plurality of supporting hooks mounted on the stops adjacent the inner sash in such a manner as not to interfere with the outer sash, said hooks extending inwardly across the path of the lower the innermost ones of said stops, a ventilator panel having slots through which said hooks project tohang it in the window, and ventilating means mounted on one side of said panel, said means overbalancing the panel to cause it to turn on said hooks and hang with its upper edge in the path of the lower sash and its lower edge in the path of the upper sash when said panel is in its normal position, and saidhooks permitting the panel to he slipped out of the planes of the sash when it is desired to raise both of them to the top of said window frame.

3. The combination of a metallic panel having over turned top and bottom sides and slots located adjacent its upper edge, retractable end pieces fitted into said overturned edges and projecting from said panel, mounting plates comprising a main portion adapted to be rigidly at-, tached to a support and a tongue spaced from l5 panel being hung by projecting said tongues through said slots and adjusted by sliding it longitudinally of said tongues to the desired position.-

4. The combination of a rigid metallic panel, a ventilating means mounted thereon, extensible end pieces mounted onthepanel and slidable with respect thereto to increase its effective length, and means for hanging said panel in a window, said means being disposed within and on the frame of the window and permitting the upper sash of the window to befully raised and permitting the panel to be swung about its upper edge as a pivotal axis to bring it into the path of that sash when the sash'is lowered, said means including laterally extending portions providing for movement of said panel and ventilating means out of the path of the lower sash of said window,

p 5. In combination with a rigid metallic panel having overbalancing ventilatingimeans mounted thereon, a U-shaped hook member extending in a plane substantially normal to said panel for supporting said panel from the upper stop ofa, window frame, said panel being freely slidable laterally on said' hook member to move it suc'-. cessively from the path of the upper window sash through the path .of the lower window sash to a point outside of said paths to provide for raising-both sashes to their upper limiting positions,and a turned up portion on said hook member preventing lateral sliding of said panel past said last named point.

6. In combination, in a window frame, a pair of spaced U-shaped supporting members secured tothe upper sash stops of said frame and having their open ends extending inwardly of said frame, ventilating means including'a metallic panel depending from and pivoted about said members within said frame, said panel being laterally, slidable upon said members to position it with respect to the window sashes in said frame, and means on said hooks limiting lateral movement of said panel.

'7. In combination, in a window frame, a pair of spaced U-shaped supporting members secured across the upper sash stops of said frame and extending across the stops of the lower window sash to a point outside of said stops, ventilating means including a metallic panel pivoted upon and depending from said members and normally maintained in over-balanced position to extend angularly across the paths of the window sashes, said panel being slidable laterally on said members to position it out of the paths of said sashes when moved in one direction, and to extend angularly from said members into the path of the upper window sash when moved in the opposite direction.

8. A hook for supporting ventilating means including a metallic panel within a window frame,

comprising an upper planar portion having open-. ings therein receiving means for securingsaid hook to the upper sash stop of said frame, an integral tongue portiondoubled back and extending a parallel to said upper portion of said hook in spaced relation thereto, and an up turned tip iting sliding movement .of said panel upon said tongue portion.
